synthesis | a route for the production of GABA via putrescine in Corynebacterium glutamicum. A putrescine-producing recombinant Corynebacterium glutamicum strain is converted into a GABA producing strain by heterologous expression of putrescine transaminase PatA and gamma-aminobutyraldehyde dehydrogenase PatD genes from Escherichia coli. The resultant strain produces 5.3 g per l of GABA. GABA production is improved further by adjusting the concentration of nitrogen in the culture medium, by avoiding the formation of the by-product N-acetylputrescine and by deletion of the genes for GABA catabolism and GABA re-uptake. GABA accumulation by this strain is increased by 5% to 8.0 g per l, and the volumetric productivity is increased to 0.31 g per l and h | Escherichia coli |
